Which has greater number of atoms a gram of helium or a gram of neon?
Neon is larger because it has more protons, electrons, and neutrons. Look at the element's Atomic Mass for an idea of its size.
How much is 1 gram in metric system?
1 gram is equal to 0.001 kilograms in the metric system.
How much does helium cost for one gram?
Helium isn't usually sold by the gram, but by volume. Typical prices for a, say, 15 cubic foot container (that's 15 cubic feet at STP; the container itself is significantly smaller) would be around $50. A cubic foot is about 28.3 L, so that's about $0.12 per liter. A mole of ideal gas at STP is 22.4 L, and a mole of helium would have a mass of 1 gram, so, roughly $2.70 per gram is about right. As with most things, you can get a much better price if you buy in bulk.
How much is 6350 kg in a gram?
6350 kg is equal to 6,350,000 grams.
How much is it when you divide a gram in to 20?
When you divide 1 gram into 20 equal parts, each part would be 0.05 grams. This is calculated by dividing 1 gram by 20.
