Question

mass of 48.176X 1023 molecules of ch4

Answer 1

Mass of 48.176×10^23 of CH4 then-

$\blue{\boxed{\Huge{moles=\frac{given \: mass}{molar \: mass}}}}$

and

$\blue{\huge{\boxed{moles=\frac{no. \: of \: molecules}{avogadro \: number}}}}$

$\red{\boxed{\huge{ \frac{given \: mass}{molar \: mass} = \frac{no. \: of \: molecles}{avogadro \: number}}}}$

using this equation-
$\frac{m}{16} = \frac{48 \times {10}^{23} }{6 \times {10}^{23} } \\ m = 8 \times 16 \\ m = 128$

$\boxed{\huge{Mass=128gm}}$
