determine the mass of the first sample alone. Calculate the amount (number of moles) of a substance in the bag. Calculate the number of particles of the substance which are present in the bag (include correct particle as a unit). show all calculations for the first substance including units and a final statement with the correct number of signifigant digits. Repeat the steps above with the other 4 samples (that i'll give you chatgpt) but put the calculation results in a table. You do NOT need to write calculations for the other 4 substances in the report, just enter data substances 1-5 (mass, molar mass, amount, number of particles) in a table

Calculate molar mass of each chemical: CaCO3, CaCl2, and Na2CO3. Record on data sheet.

A sample of an unknown compound is vaporized at 200.°C. The gas produced has a volume of 2230.mL at a pressure of 1.00atm, and it weighs 5.98g.Assuming the gas behaves as an ideal gas under these conditions, calculate the molar mass of the compound. Be sure your answer has the correct number of significant digits.

Lets assume the liquid in problem 1 above is H2O2 (hydrogen peroxide).  Below is the data table of the three mass measurements: A, B, and C. Determine the mass of H2O2 using the data from measurement C. 1 point60. g60 g146 g206 g25.64 g102 g102.00 gClear selection

Rebecca has samples of different types of metal, and she wants to find the density of each. First, she measures the volume of each sample. Now she needs to measure the samples' masses.Which of the following tools should Rebecca use to measure the mass of each sample? A. graduated cylinder B. balance C. measuring tape D. calipers
