recall that density is mass per unit volume, or
d = m/V
d = 100/200
d = 0.5 g/mL
hope this helps~ :)
2. An object will sink in a liquid if the density of the object is greater than that of the liquid. The mass of a sphere is 9.83 g. If the volume of this sphere is less than __________ cm3, then the sphere will sink in liquid mercury (density = 13.6

A flask weighs 95 g when empty. When filled with 200 mL of a certain liquid, the weight is 328 g. What volume (in milliliters) would 1,000 g of the liquid occupy? I am confused on set up I know d=m/v so v=m/d
A machine is used to fill soda bottles in a factory. The bottles are labeled as containing 2.0 liters, but extra room at the top of the bottle allows for a maximum of 2.25 liters of soda before the bottle overflows. The standard deviation of the amount of
A cubical block of density rB and with sides of length L floats in a liquid of greater density rL. (a) What fraction of the block’s volume is above the surface of the liquid? (b) The liquid is denser than water (density rW) and does not mix with it. If
Assume that a round bottom flask holds 100 mL and the distilling head has an internal volume of 12 mL in the vertical section. At the end of a distillation, vapor would fill this volume, but it could not be forced through the system. No liquid would remain
Which of the below data sets has the lowest standard deviation? You do not need to calculate the exact standard deviations to answer this question. 0, 1, 2, 3, 4, 5, 6 0, 25, 50, 100, 125, 150, 1000 0, 1, 3, 3, 3, 5, 6 0, 0, 0, 100, 200, 200, 200
A density bottle weighs 70g when filled with water and 94g when filled with liquid A. Find the density of liquid A given that density of water is 1000kg/m³
A brewery's filling machine is adjusted to fill bottles with a mean of 31.5 oz. of ale and a variance of 0.003. Periodically, a bottle is checked and the amount of ale noted. (a) Assuming the amount of fill is normally distributed, what is the probability
A solid has a mass of 200g in air and when partly immersed in a certain liquid it has a mass of 160g. Given that the relative density of the liquid is 0.80, calculate the volume of the solid immersed in the liquid.
Perpare 500ml of 1M HCl solution from a bottle of concentrated 37%(W/W) HCL stock with a density of 1.19g/ml. 37%= 37/100 x 100 therefore mass is 37g molarity = mol/vol 1= mol/0.5 mol=0.5 mass of Hcl needed = molxmr mass = 0.5 x 36.5 mass = 18.25g
