Molarity of 2%W/V of NaOH is

TiliK225 [7]

Assume it is 1 litre and weighs 1kg.
2 percent of 1 kg is 20g.
20g divided by molar mass of NaOH.
20g divide by 40 = 0.5 mole
0.5 mole in a litre would be 0.5M
That is the answer: 0.5M

The molecular formula for butane is C4H10. Determine the percent composition for

masya89 [10]

%Mass

Ar C = 12 g/mol, Mr C₄H₁₀ = 58 g/mol, Ar H = 1 g/mol

$\tt C=\dfrac{4.12}{58}\times 100\%=82.8\%\\\\H=100\%-82.8\%=17.2\%$

$\tt H=\dfrac{10.1}{58}\times 100\%= 17.2\%$
