Answer:
d = 2.57456 g/cm³
Explanation:
Given data:
Length of metal bar = 853cm
Width = 24 cm
Height = 10 cm
Mass = 527064 g
Density of metal = ?
Solution:
Volume of metal bar:
Volume = length × width × height
Volume = 853 cm × 24 cm × 10 cm
Volume = 204720 cm³
Density:
d = m/v
d = 527064 g / 204720 cm³
d = 2.57456 g/cm³

How many moles are equal to 157.8g of CaCl2?
Answer:
Explanation:
K: 157.8 g CaCl2
U: ? mol CaCl2
1Ca = 1(40.08) = 40.08
2 Cl = 2(35.45) =+70.90
110.98
157.8 g CaCl2 1 mol CaCl2
x
1 mol CaCl2 110.98 g CaCl2
