Question

Calculate the mass of the solute in 0.1 L of a 5.04x103 M cholesterol solution (C27H460

Answer 1

Question

Calculate the mass of the solute in $0.1L$ of a $5.04×10^{-3}M$ cholesterol solution $C_{27}H_{46}O$

SOLUTION

Molar mass of $C_{27}H_{46}O$

$=386.65g/mol$

Moles in $0.1\>L$ $=0.1×5.04×10^{-3}\\=5 .04×10^{-4}moles$

Mass $=5.04×10^{-4}×386.65$

$=0.19487g$
