Answer:

Q = 2997.69 J

Explanation:

Given that,

The mass of ice, m = 15.6 grams

The temperature increases from -8.76 degrees Celsius to 85.9 degrees Celsius.

The specifc heat of ice is 2.03 J/g°C

We need to find the amount of energy required. The formula for energy required is given by :

Q=mc\Delta T\\\\=15.6\times 2.03\times (85.9-(-8.76))\\\\=2997.69\ J

So, the required heat is equal to 2997.69 J.

PLEASE PLEASE HELP<br> Calculate the mass of 3.4 moles of nitric acid (HNO3)
Elza [17]
Molar mass of nitric acid (HNO3) =atomic mass of hydrogen + atomic mass of nitrogen +3x atomic mass of oxygen . The molar mass of nitric acid (HNO3) is 63.0144 gram per mole, but you have 3.4 moles. Therefore; the answer is 63.0144 g/mole x 3.4 moles = 214.24896 grams.

Calculate the moles and grams of solute in each solution. D. 2.0 L of 0.30M Na2SO4. I already have A, B, and C. Thanks!
e-lub [12.9K]
Find the number of moles
C = n / V
C(Concentration) = 0.30 moles / L
V ( Volume) = 2 L
n = ??
n = C * V
n = 0.30 mol / L * 2 L
n = 0.60 mol


Find the molar mass
2Na = 23 * 2 = 46 grams
1S   = 32 * 1 = 32 grams
O4   = 16 * 4 = 64 grams
Total =            142 grams / mol

Find the mass
n = given mass / molar mass
n = 0.06 mol
molar Mass = 142 grams / mol
given mass = ???

given mass = molar mass * mols
given mass = 142 * 0.6
given mass = 85.2 grams. 

85.2 are in a 2 L solution that has a concentration of 0.6 mol/L
