What is the mass of 3.75 moles of NaCI? ( Na= 22.99g/mol, CI= 35.45 g/mol)
seraphim [82]

Answer:

219.15 grams

Explanation:

What is the mass of 3.75 moles of NaCI? ( Na= 22.99g/mol, CI= 35.45 g/mol)

Mole of Na = 22.99g

Mole of Cl = 35.45g

For NaCl we have ratio of 1:1, so we have 1 Na for every Cl

So we just add the two together to get the molar mass of NaCl which is

22.99 + 35.45 = 58.44g/mol

And we know we have 3.75 moles of NaCl so we multiply that by the molar mass of NaCl to get our answer

3.75 x 58.44 = 219.15grams

What is the kinetic energy of a 478 kg object that is moving with a speed of 15m/s
AVprozaik [17]

Answer:Kinetic energy = (1/2)*mass*velocity^2

KE = (1/2)mv^2

KE = (1/2)(478)(15)^2

KE = 53775J

Explanation:

Kinetic energy = (1/2)*mass*velocity^2

KE = (1/2)mv^2

KE = (1/2)(478)(15)^2

KE = 53775J
