(1)假设容器的体积为VL,质量为m,
则有:m+
VL
22.4L/mol ×32g/mol=79g,m+
VL
22.4L/mol ×28g/mol=71g,
解之得:V=44.8,m=15g,
答:此容器的容积为44.8L;
(2)盛满某气体X时,质量为103g,设气体X的摩尔质量为M,
则有:15g+
44.8L
22.4L/mol ×M=103g,
解之得:M=44g/mol,
答:气体X的摩尔质量为44g/mol;
(3)在标况下该容器中盛满氯气时的总质量为:15g+
44.8L
22.4L/mol ×71g/mol=157g,
答:在标况下该容器中盛满氯气时的总质量为157g.
