Hoped I help :)
1.56 mole of H₂SO₄ is present in the solution.
Molarity is defined as the mole of solute per unit litre of the solution. Mathematically, it is expressed as:
[tex]Molarity = \frac{mole}{volume }[/tex]
With the above formula, we can obtain the number of mole of H₂SO₄ present in the solution. This can be obtained as follow:
Volume = 1.63 L
Molarity = 0.954 M
Mole of H₂SO₄ =?[tex]Molarity = \frac{mole}{Volume}\\\\0.954 = \frac{mole}{1.63}[/tex]
Cross multiply
Mole = 0.954 × 1.63
Mole of H₂SO₄ = 1.56 moleTherefore, 1.56 mole of H₂SO₄ is present in the solution.

A reaction was suppose to produce 20 L of gas. Only 12 litters of gas were produced in the lab. What is the percent yield for this reaction?
Answer:
[tex]\boxed {\boxed {\sf 60 \%}}[/tex]
Explanation:
Percent yield is a ratio of the actual yield to the theoretical yield. It is found using this formula:
[tex]\% \ yield= \frac {actual \ yield}{theoretical \ yield} *100[/tex]
The actual yield is 12 liters, because that was actually produced in the lab.
The theoretical yield is 20 liters, because that was the expected yield.
[tex]\% \ yield= \frac {12 \ L}{20\ L} *100[/tex]
[tex]\% \ yield= 0.6*100[/tex]
[tex]\% \ yield= 60[/tex]
For this reaction, the percent yield is 60%.

Answer:
Mass ratio:
a. Approximately [tex]51.2\%[/tex].
b. Approximately [tex]35.3\%[/tex].
c. Approximately [tex]43.2\%[/tex].
Explanation:
Look up the relative atomic mass of each element on a modern periodic table:
[tex]\rm Mg[/tex]: [tex]24.305[/tex].[tex]\rm S[/tex]: [tex]32.06[/tex].[tex]\rm O[/tex]: [tex]15.999[/tex].[tex]\rm H[/tex]: [tex]1.008[/tex].[tex]\rm Li[/tex]: [tex]6.94[/tex].[tex]\rm C[/tex]: [tex]12.011[/tex].[tex]\rm Al[/tex]: [tex]26.982[/tex].[tex]\rm N[/tex]: [tex]14.007[/tex].For example, the relative atomic mass of [tex]\rm Al[/tex] is [tex]26.982[/tex]. Hence, the mass of one mole of [tex]\rm Al\![/tex] atoms would be (approximately) [tex]26.982\; \rm g[/tex].
Calculate the formula mass of [tex]\rm H_2O[/tex]:
[tex]\begin{aligned} & M({\rm H_2O}) \\ &= 2 \times 1.008 + 15.999 \\ &= 18.015\; \rm g \cdot mol^{-1}\end{aligned}[/tex].
Calculate the formula mass for each of the hydrates:

[tex]\begin{aligned}& M({\rm Al(NO_3)_3 \cdot {9\, H_2O}}) \\ &= 26.982 + 3 \times (14.007 + 3 \time 15.999) \\ &\quad \quad + 9 \times (2 \times 1.008 + 15.999) \\ &= 375.129\; \rm g \cdot mol^{-1}\end{aligned}[/tex].
The mass of [tex]1\; \rm mol[/tex] of [tex]{\rm MgSO_4 \cdot {7\, H_2O}}[/tex] formula units is [tex]246.466\; \rm g[/tex].
There are seven mole of [tex]\rm H_2O[/tex] formula units in that many [tex]{\rm MgSO_4 \cdot {7\, H_2O}}[/tex] formula units. The mass of that [tex]7\; \rm mol[/tex] of [tex]\rm H_2O\![/tex] formula units would be [tex]7 \; \rm mol \times 18.015\; \rm g \cdot mol^{-1} = 127.105\; \rm g[/tex].
Hence, the percentage mass of [tex]\rm H_2O[/tex] in [tex]{\rm MgSO_4 \cdot {7\, H_2O}}[/tex] would be:
[tex]\begin{aligned}\frac{127.015\; \rm g}{246.466\; \rm g} \approx 51.2\%\end{aligned}[/tex].
Similarly:

Which of the following is a way that the pressure of an object can be decreased?
Answer:
There is no attachment
however, u could remove the object
Answer:
The pressure of an object, is made off of atoms, and the hotter they are, the quicker they'll go. Meaning they're under pressure, and the atoms begin to start to melt, and as it'll go the object will start catching on fire. The way how an object and atom are out of pressure is to be cooled, the cooling of an atom freezes the atom, which'll mean they wont move or do anything matter of fact. Thus, the cooling of atoms is how you take an object/atom out of pressure.

Consider 2 pots of water. Each pot has the same diameter, but pot A is deeper than pot B and so there is more water in pot A. If both pots are exposed to the same amount of heat for 5 minutes, which pot will contain the hottest water after 5 minutes? Why?
Answer:
POT B
Explanation:
Because Pot B contains lesser amount of water, it is going to have the hottest water compared to pot A.
Since the amount of heat is constant, in pot B less water molecules would share the heat, compared to pot A where a larger amount of water would have to share the heat.

The specific heat capacity of water is 4.184 J/g°C. How much heat is required to heat 500.0 g of water from 50.0°C to 100.°C?
Answer:
104600 Joules
Explanation:
The quantity of Heat Energy (Q) required to heat a substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Since, M = 500.0 g
C = 4.184 J/g°C
Φ = 100°C - 50°C = 50°C
Q = 500g x 4.184J/g°C x 50°C
Q= 104600 Joules
Thus, it takes 104600 Joules of heat energy to heat the water
Answer: 104,600
Explanation: subtract final temp from initial temp = 50 then multiply by grams = 25,000 then multiply by J = 104,600
