### Chemistry Math - Solving a Formula

By Laurel Maney

Students use algebra to rearrange formulas and solve for the missing volume, density, or mass quantity.

A friend has a gem that he claims to be a diamond. This gem is 47 carats and has a volume of 1.59 mL. What is the density, p, of this gem? (1g=5.0 carats).

How many moles of nitrogen gas, N2, are in a sample that occupies 35.0 L at a pressure of 3.15 atm and a temperature of 852 K? R= 0.0821 L atm/mol K.

30 ml of a mixture of carbon monoxide and carbon dioxide by adding 10 ml of oxygen by the explosion was current-spark. gas mixture generated caustic Potash solution by adding 5 ml of the remaining left shaken. Mix the amount of material?

0.53g of acetanilide was subjected to kjeldahl determination and the ammonia produced was collected in 50cm^3 of 0.50M H2SO4. on dilution to 250cm^3, the acid was titrated against 25cm^3 portion of 0.05M sodium carbonate solution.13.60cm^3 of acid was required for each titration. what is the percentage of nitrogen in acetanilide?

(3.75 km/hr)(4.000 hr)

Find the final volume of gas at 100 K, if volume of gas is 5 L at 20 K
