Question

A 0.5dm3 flask contains gas A and 1dm3 flask contains gas B at the same tperature. If density of A=3g/dm3 amd of B=15.g/dm3 and the molar mass

Answer 1

P V /n = R T

P_1 V_1 /n_1 = P_2 V_2 /n_2  

P_1 (0.5) /n_1 = P_2 (1) /n_2

Density of 1st solution is

d_1 = 3 * 10^-^3 = m_1 /V_1

3 * 10^-^3 = m_1 /0.5

1.5 * 10^-^3 = m_1  

n_1 = m_1 /M_1

=
