How many formula units in 47.63 grams?
It depends on the substance and its molar mass.In order to convert from grams to formula units, you must first convert grams to moles, then moles to formula units (grams --> moles --> formula units).1. Divide the mass (g) of the given substance by the substance's molar mass.2. Multiply the number of moles found in Step 1 (above) by Avogadro's number (6.022 x 1023).---- Mass substance ----- X 6.022 x 1023 formula unitsMolar mass substanceCONVERSION FACTOR47.63g substance x 1 mol substance ---- x ----- Avogadro's number///////////////////// molar mass (g) substance ////// 1 mol substance
What formula is e equals pt?
The formula for energy. E is for energy(Units = Joules) P is for power(Units = Watts) T is for time(Units = Seconds)
Calculate the volume of a cylinder given its radius is 4 and its length is 9 to the nearest whole number?
Formula for calculating the volume of a cylinder = pi*radius2*length giving your answer in cubic units. Therefore: pi*42*9 = 452.3893421 cubic units. To the nearest whole number: 452 cubic units.
What is the formula to calculate density and units?
Density = Mass/Volume. Conversion between units will depend on what the two units are.
What is the number of formula units that are in 5.68 moles of magnesium oxide?
