No. of moles * molar mass of Cu2CrO4
2.55*335
Answer:
1.7g
Explanation:
use the formula for molarity is equal to moles/ volume then make moles subject of the formula then calculate. Later use the formula mass is equal to moles times molecular mass
Answer: I think it could be Decomposition
Explanation: I think is composition because decomposition starts by being together and ends up as two
This is the equation balanced:
<span>BaCl2(aq) + Na2CO3(aq) = BaCO3(s) + 2 NaCl(aq)
Then the coefficient in front of Na Cl is 2.
Answer: 2

The answer is 12 mL.
When dealing with water, the mass in grams is the same as the volume in milliliters. Thus, if the rain has a mass of 12g, the volume is 12mL.
