From the information we have, this block of brown sugar has a volume of 8cm3
The mass of the block is 12. 9 grams.
We need to find out the density of the sugar.
For a solid material the formula for calculating density is given as:
Density = mass / volume
Therefore we simply fit in the above given values into this formula, so:
Density = 12.9 / 8
Density = 1.61
Therefore the density of the block of sugar is 1.61g/ml

Answer:
156.86 g / mol
Explanation:
We start from the molarity law
Cm = n / V
n = w / M
then
Cm = (w / M) / V
Cm = w / (M × V)
where:
Cm is the molarity
n number of moles
w a mass of the solute
M is the molar mass of the solute (which is needed)
V the volume of the solution in liters
Then the M can be calculated as following:
M = w / (Cm × V)
M = 100 / (0.75 × 0.85) = 156.86 g / mol
