Mass Density given Number density Solution

Follow our step by step solution on how to calculate Mass Density given Number density?

FIRST Step Consider the formula

ρ = \frac{n \cdot M molar}{[Avaga-no]}

Next Step Substitute values of Variables

∴

ρ = \frac{101/m³ \cdot 44.01g/mol}{[Avaga-no]}

Next Step Substitute values of Constants

∴

ρ = \frac{101/m³ \cdot 44.01g/mol}{6E+23}

Next Step Convert Units

∴

ρ = \frac{101/m³ \cdot 0.044kg/mol}{6E+23}

Next Step Prepare to Evaluate

∴

ρ = \frac{10 \cdot 0.044}{6E+23}

Next Step Evaluate

∴

ρ = 7.3080324346321E-25kg/m³

LAST Step Rounding Answer

∴

ρ = 7.3E-25kg/m³
