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:
Iron(III) Chlorate Fe(ClO3)3 Molecular Weight
Explanation:
Molecules which are deficient or poor of electrons are called electron deficient molecules.
Hope this helps!
Answer:
= 200 mL
Explanation:
Using the dilution formula;
M1V1 = M2V2 ;
Where, M1 is the concentration before dilution, V2 is the volume before dilution, while M2 is the concentration after dilution and V2 is the volume after dilution.
M1 = 2.0 M
V1 = 50 mL
M2 = 0.50 M
V2 = ?
V2 = M1V1/M2
= ( 2.0 × 50 )/ 0.5
= 200 mL
Therefore, the volume after dilution will be, 200 mL
Answer:
The total pressure will be 1, 021 atm
Explanation:
We apply Dalton's law, where for a gas mixture the total pressure is the sum of the partial pressures of each gas that makes up that mixture. The unit of pressure is converted into atm:
760mmHg----1 atm
542mmHg----x=(542mmHgx 1 atm)/760mmHg=0,713 atm
234mmHg----x=(234mmHgx 1 atm)/760mmHg=0,308 atm
Pt=P Ne + P At= 0,713 atm + 0,308 atm= <em>1, 021 atm</em>
