Answer:
<h2>102.5166</h2>
Explanation:
Molar mass of N2 = 28.01
3.66 moles x 28.01 grams/mole = 102.5166
M = n/V
.5M = n/.100 L
n = .1 L * .5M
n= .05 mols of MgCl2
mass of MgCl2 = .05 mols of MgCl2 * 95.211 grams/ 1 mol of MgCl2
mass of MgCl2 = 4.76 grams
4.76 grams of MgCl2 is needed to make 100 ml of a solution that is .500M, in chloride ion. Bolded = confused
Answer:
He needs to add 4 mL of the 0.5 M solution to 6 mL of water.
Answer:
The answer would be C 214g
Explanation:
890j of heat causes 4.6°c increase in temperature
specific heat of aluminium after is o.9022 j /g°c
now by using the formula .The mass of aluminium would be c that is 214 g
