Answer: Thus there are 88.4 g of calcium bromide.
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number of particles.
Molar mass of = 40.1 (1)+ 2(79.9) = 199.9
To calculate the moles, we use the equation:
Thus there are 88.4 g of calcium bromide.
Answer:
2.89 g/cm^3
Explanation:
Since density equals mass over volume (or also seen as ), simply divide 66.5 grams by 23.0 cm. This will output an answer of 2.89 g/cm^3.
