Answer:
M=0.15
Explanation:
138 g AgNO -> 1 mol AgNO
10 g AgNO -> x
x= (10 g AgNO * 1 mol AgNO)/138 g x=0.07 mol AgNO
450 mL=0.45 L
M= mol solute/L solution
M= 0.07 mol AgNO/0.45L
M=0.15

Lithium, it has an atomic number of about 3
Answer:
40°C.
Explanation:
A calorie is defined as the amount of energy needed to raise the temperature of 1 gram of water through 1 °C. In the same way, a kcal would be defined as the amount of energy needed to raise the temperature of 1 kilogram of water through 1 °C.
Based on this definition, 100kcal will increase the emperature of the water in:
100kcal / 2,5kg = <em>40°C</em>

The ions present in the solution of Na₃PO₄ are:
3Na⁺¹ and 1PO₄⁻³
there are 3 sodium ions (Na⁺¹) are present, these are cations (+).
And 1 phosphate ion (PO₄⁻³) is present, this is anion (-),
When these cations and ions meet together a compound is formed, in this case 3 sodium ions make a bond with 3 oxygens of phosphate and makes a compound of sodium phosphate.
