Answer:
1.22 mol Ca
Explanation:
Molar mass (Ca)=40.1 g/mol
49.0 g* 1 mol/40.1 g ≈ 1.22 mol Ca
Answer:
110.984 ?
i apologize if i'm wrong, you can report it if im wrong
have a good day/ night
Explanation:
Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship, when temperature is held constant i.e PV = constant. Therefore, P1V1 = P2V2--(i) ( P1 = initial pressure, P2= final pressure, V1= initial volume, V2= final volume). P1=930 torr, P2= 970 torr, V1= 95 ml, V2=?.
Put these values in equation (i),
930 torr x 95 ml = 970 torr x V2. Therefore, V2 = 91.08 ml.
