Question

How many grams is 9.03 moles of MgSO4? Round answer to three significant figures.

Answer 1

Dados:
m (mass) = ?
n (Number of mols) = 9.03 mols
MM (Molar Mass) of MgSO4
Mg = 24 u
S = 32 u
O = 4*16 = 64 u
-----------------------------
MM of MgSO4 = 24+32+64 = 120 g/mol

Formula:


`n = (m)/(MM)`

Solving:

`n = (m)/(MM)`

`9.03 = (m)/(120)`

`m = 9.03*120`

`\boxed{\boxed{m = 1083.6\:g}}\end{array}}\qquad\quad\checkmark`
