Solution

The correct option is B $0.0177$
$1.00 m$ solution means $1 mole$ solute is present in $1000 g$ water.
$n_{H_{2} O} = \frac{1000}{18} = 55.5 mol H_{2} O$
$X_{solute} = \frac{n_{solute}}{n_{solute} + n_{H_{2} O}} = \frac{1}{1 + 55.5} = 0.0177$

The correct option is B 0.01771.00 m solution means 1 mole solute is present in 1000 g water. nH2O=100018=55.5 mol H2O Xsolute=nsolutensolute+nH2O=11+55.5=0.0177

The correct option is B $0.0177$
$1.00 m$ solution means $1 mole$ solute is present in $1000 g$ water.
$n_{H_{2} O} = \frac{1000}{18} = 55.5 mol H_{2} O$
$X_{solute} = \frac{n_{solute}}{n_{solute} + n_{H_{2} O}} = \frac{1}{1 + 55.5} = 0.0177$
