No of moles of MgCl2 = weight of MgCl2 / Molecular weight of MgCl2
Weight of MgCl2 =moles of MgCl2 x molecular mass of MgCl2
= 8.90 x 95=845.5 gm
Answer:
An Atom
Explanation:
An atom is the smallest unit of matter
Answer:
new Volume of gas=360L
Explanation:
Assume that given gas follow the ideality nature of gas
Assuming that temperature is constant;
P1 and V1 are the initial parameter of gas
and p2 and V2 are the parameter after increasing the pressure
according to boyle 's law pressure is inversly proportional to the volume at constant temperature.

given value of volume and gas
P1=90kPa
V1=600L
P2=150kPa
V2=?
After putting all values we get;
V2=360L
new Volume of gas=360L
