0No. 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 kilometers is 13,583,000 inches.

345 pounds = 24.6 stone

1 meter = 100 cm 345 cm = 3.45 meter

There are about: 8/5 times 345 = 552 kilometers

345 L = 345 000 mLTo convert from L to mL, multiply by 1000.

345 has eight factors: 1, 3, 5, 15, 23, 69, 115, 345.

345 kg = 345 000 gTo convert from kg to g, multiply by 1000.

345 miles is equal to 1821600 feet.

345 liters = 91.14 US gallons.

345 ml is approximately 1.521 cups

345 pounds is equal to 156.49 kg

There are about: 345/2.54 = about 135 to 136 inches

1 meter = 100 centimeters345 meters = (345 x 100) = 34,500 centimeters

1 pound = 16 ounces 345 pounds = 16 x 345 ounces = 5,520

the answer comes from taking twelves away from 345, and the answer represents how many twelves were taken to reproduce 345. 28.75

There are 1000 metres in one kilometre. Therefore, 345 metres is equal to 345/1000 = 0.345 kilometres.

345 liters = 91.14 US gallons.

345 ft = 0.105 km (to 3 dp)

345 ÷ 24 = 14 days 9 hours

As a product of its prime factors: 3*5*23 = 345
