The answer is 54g of mass
Explanation:
Using the formula
n = m/Mm
n - mole
m - mass
Mm - molar mass
Since we are given the mole of water to be 3
Let's calculate the molar mass of H2O
H is 1
O is 16
Mm = 1 * 2 + 16
= 2 + 16
= 18g/mol
Using the formula above,
n = m / Mm
n = 3
m = we are looking for
Mm = 18g/mol
3 = m / 18
so, m = 18*3
= 54g
