Question

已知甲、乙溶質(zhì)的質(zhì)量分數(shù)與溶液密度的關(guān)系如下表所示：

溶質(zhì)的質(zhì)量分數(shù)	甲溶液密度╱g·cm-3	乙溶液密度╱g·cm-3
1%	0.95	1.02
5%	0.92	1.04
9%	0.90	1.07

甲物質(zhì)的1%的溶液與9%的溶液等體積混合，乙物質(zhì)的1%的溶液與9%的溶液等體積混合，下列敘述中，正確的是

A．混合后，甲、乙溶液中溶質(zhì)的質(zhì)量分數(shù)均大于5%

B．混合后，乙溶液中溶質(zhì)的質(zhì)量分數(shù)大于5%，甲溶液中溶質(zhì)的質(zhì)量分數(shù)小于5%

C．混合后，甲溶液中溶質(zhì)的質(zhì)量分數(shù)大于5%，乙溶液中溶質(zhì)的質(zhì)量分數(shù)小于5%

D．混合后，甲、乙溶液中溶質(zhì)的質(zhì)量分數(shù)均等于5%
