If grams/molar mass=moles, then first the molar mass of the compound must be found. CaCl2 has a molar mass of 110.984. Divide the number of grams, 15.5, by 110.984, and you get the number of moles. Now, seeing as calcium is not diatomic like oxygen or chlorine, there needs to be no conversion between the number of moles of calcium in the compound and the number of moles of calcium outside of the compound. atoms, the number of calcium atoms in the compound divided by one mole of the compound will give us the ratio. Conveniently enough, that ratio is one calcium atom per molecule of calcium chloride, meaning that for every one mole of calcium chloride, 1 mole of pure calcium can be extracted. So once you find the number of mole of CaCl2, that is the number of moles of calcium as well. This may be a little difficult to grasp, but I'm sure that your teacher, if you're a student, will be able to explain why rather well.

1 km 155 m is equal to 1155 meters. This can be calculated by converting 1 km to meters (1000 m) and adding it to the given 155 meters.
One inch is 2.54cm so divide centimeters by 2.54: 155 / 2.54 = about 61.02 inches.
There are 0.000155 kilowatts (kW) in 155 milliwatts (mW).
There are 15.5 cm in 155 mm. To convert millimeters to centimeters, divide by 10 since there are 10 millimeters in a centimeter.
To find the moles of sodium chloride solute in 155 grams of an 85.5% solution, first calculate the mass of sodium chloride present in the solution (mass percent x mass of solution). Then, convert the mass of sodium chloride to moles using its molar mass (58.44 g/mol). This will give you the number of moles of sodium chloride solute in the solution.
Well, Ca has an atomic mass of 40, so one mole of Ca (6.022x1023 atoms) equals 40g.To get 5kg of Ca, you would times the 40g (one mole) by 125.5kg of Ca has 125x(6.022x1023), or602200000000000000000000 atoms.
To determine the number of sulfur atoms in 155 g of sulfur, you first need to calculate the number of moles of sulfur present. The molar mass of sulfur is approximately 32.06 g/mol. By dividing the given mass by the molar mass, you find that there are approximately 4.83 moles of sulfur. Since one mole of sulfur contains Avogadro's number of atoms (6.022 x 10^23), you can calculate that there are approximately 2.91 x 10^24 sulfur atoms in 155 g of sulfur.
155 grams
155 grams is 5.47 ounces.
155 mph is 249.448 kph
155 miles = 249.45 km
155 kilogram = 24.4 stone
155 m = 508.53 ft
155 divided by 15 = 10.3333333
155 pounds = 11.07 stone.
To find out how many times 14 goes into 155, you can divide 155 by 14. When you do the calculation, 155 divided by 14 equals approximately 11.07. This means 14 goes into 155 a total of 11 times, with a remainder.
