mol= massa/Mr= 7g/2.14= 1/4 mol. V=mol x R.T/P = 0,25 x 0,082x (273+37)/0,92 atm = 6,9 L
n= mol x L = 0,25 x 6,02. 10^23 = 1,505 x 10^23 (nomor 1)
oh ma'af maksudnya yang diatas itu x, kalo n= mol= m/Mr = 7/2.14 = 1/4 mol :D
2). Mol= V.P/RT = 0,615.1/300.0,082= 0,025. Mr= massa/mol=0,75/0,025=30. jadi Mr=30
