Question

mass of 10^-3 moles of MgSO4
​

Answer 1

$\boxed{\bf{\blue{\longrightarrow Answer}}}$

• ${Mole = \frac {given \: mass}{molecular \: mass}}$
• $= 24 \times 1 + 32 \times 1 + 16 \times 4 \\ = 24 + 32 + 64 \\ = 120$
• $mole \times molecular \: mass = given \: mass$
• $= {10}^{ - 3} \times 12 \times 10$
• $= 12 \times {10}^{ - 2} = 0.12u$
• Hope it helps!
