Question

b Calculate the mass of 0.5 moles to Ne science​

Answer 1

For calculate the mass of 0.5 moles of N2 gas we have to calculate the mass of N2 gas

there is gas of Nitrogen and nitrogen exit in divelant so mass of nitrogen is 14 gm and mass of two nitrogen will form one molecule of nitrogen gas so mass of nitrogen gass will be 28gm in one mole and we have to find the 0.5 mole of nitrogen gas so we will multiply it by 28

(0.5×28=14gm)

${\boxed{\sf{\color{blue}{Number \: of \: moles (n) = \frac{weight}{molecular \: weight} }}}}$

$\sf{Weight = n \times Molecular \: weight}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf{ = 0.5 \times 14}$

$\sf\underline{\underline{\pink{∴Mass = 7g}}}$
