Molarity = moles of solute/Liters of solution
3.45 M NaCl = moles NaCl/5 liters
= 17.25 moles
.487 Kl
No. of moles = Given mass of element or compound/ molar mass of element or compound. Molar mass of Methane(CH4) = 16 g No. of moles of Methane in 345g = 345/16=21.562 moles.
There are 345 ones in 345.
It gives the mass of copper present in .345 moles of it. 0.345 x63.5 =21.92337g
first you must have a mass in mind. eg 345 grams of Carbon divided the mass by the molar weight of the particular substance. In the case of Carbon 12 grams/mole 345 grams/12 grams/mole = 28.75 moles
345
345 yd = 1035 '
345 kilometers is 13,583,000 inches.
345 lbs. = 156.49kg
345 pounds = 24.6 stone
345 ÷ 15 = 23
1 meter = 100 cm 345 cm = 3.45 meter
