Which has more atoms 1.1 g of hydrogen atoms or 14.7g of chromium atoms?
For this you need the Atomic Mass of Cr. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.11.9 moles Cr × (52.0 grams) =618.8 grams Cr
How many moles are present in 1 g?
It depends on the substance. Remember that moles are a unit of amount, and one mole is 6.02 × 1023 atoms. So if you have lead and hydrogen, they are obviously going to weigh differently. It would take far fewer atoms of lead to amount to 1 gram; therefore, less moles. However, one hydrogen atom has far less mass than one lead atom, and would need more atoms (and moles) to make one gram.
How many moles of Cu are in the 148 times 10 to the power 25 atoms?
15.8 moles Cu x 6.02x10^23 atoms/mole = 9.51x10^22 atoms. There are no molecules in the element Cu (copper). Molecules are found when there are two or more atoms bound together, such as in H2 gas or H2O, etc.
What is the mass of water when 4gm hydrogen and 64gm oxygen combined together nd how?
Balanced equation first.2H2 + O2 --> 2H2OGet moles products.4 grams H2 (1 mole H2/2.016 grams) = 1.984 moles H264 grams O2 (1 mole O2/32 grams) = 2.000 moles O2I suspect hydrogen gas of limiting and driving the reaction.1.984 moles H2 (1 mole O2/2 moles H2) = 0.992 moles O2 ( you have more than this in equation )2.000 moles O2 (2 mole H2/1 mole O2) = 4.000 moles H2 ( you do not have this much and H2 will drive this reaction )1.984 moles H2 (2 moles H2O/2 moles H2)(18.016 grams/1 mole H2O)= 36 grams water produced====================
Why is there so much more in a mole of sugar than carbon?
Sugar is composed of 22 atoms of hydrogen, 12 atoms of carbon as well as 11 atoms of oxygen

Which has a greater number of atoms 3 grams of iron or 2 grams of sulfur?
In order to compare the number of atoms, one needs to first convert the masses into moles:3 g Fe x 1 mole/55.8 g = 0.054 moles Fe2 g S x 1 mole/32 g = 0.063 moles STherefore, 2 g of sulfur contains more atoms than does 3 g of Fe. This is because 1 mole of ANY element contains 602x10^23 atoms, so the more moles you have, the more atoms you have.
How many atoms are there in 2 moles of hydrogen?
In 1 mole of anything there is 6.022 x 10^23 of that item. In 1 mole of chairs there is 6.022 x10^23 chairs. In 1 mole of bacteria there is 6.022 x 10^23 bacteria. Likewise, 1 mole of hydrogen atoms is equivalent to 6.022x10^23 hydrogen atoms. 2 moles of hydrogen atoms is double this amount. 2 x 6.022 x 10^23 = 12.044 x 10^23, which is 1.2044 x 10^24 hydrogen atoms. This number, 6.022 x 10^23, is called Avogadro's Number. It is like the word "dozen", which means "12 of". 1 dozen bagels is 12 bagels. 1 dozen animals is 12 animals. Same concept here. Hope that helps ya.
What has more atoms 17.031 grams of ammonia or 72.922 grams of hydrogen chloride?
Molar mass of ammonia is 17.031 whereas molar mass of hydrogen chloride (or hydrochloric acid) is 36.461. Hence if given masses, there is 1 mole ammonia and 2 moles HCl. Hence there is more number of hydrogen chloride.
Is 1.11 mol of Pt more or less than 6.022 x 1023 atoms and why?
6.022 x 1023 atoms comprise just about 1 mole. 1.11 moles is greater than 1 mole.
How many moles of Cu are in the 148 times 10 to the power 25 atoms?

How many hydrogen atoms are present in 1 mole of acetic acid or CH3COOH?
CH3COOH CH3COO- + H+So there is only one acidic H atom.[Only the 'bold' H atom is acidic, the 3 'methyl' H's are not!]
Which one has more atoms 10 g of Al or 10 g of Fe?
use the following formula to determine number of moles number of moles = mass given/molar mass (mass on periodic table) one mole = 6.02x10^23 particles (molecules or atoms depending on substance) hence whichever mass has the greatest number of moles has the more atoms
Which contains more atoms a mole of silver atoms or a mole of gold atoms?
they are the same. all elements have 6.022 x 1023 atoms per mole
