Question

Determine the mass in grams of 0.500 moles of Ca(OH)2

Answer 1

Answer:

37 gr is the mass in grams of 0.500 moles of Ca(OH)2

Explanation:

$mole =\frac{mass}{gram molecular mass}$

moles = 0.5

molecular mass = 1×40+2×16+2×1 = 40+32+2=74

mass = moles × molecular mass = $\frac{1}{2}$×74 = 37 gr
