How many moles are present in 6.022 x 1023 atoms of Cr?
Only one mole of copper.
How many atoms are present in a piece of sterlingsilver jewelry weighing 33.14?
How many atoms are present in a piece of sterlingsilver jewelry weighing 33.14 ? (Sterling silver is a silver-copper alloy containing 92.5% by mass.)
How many atoms are in each elemental sample 4.0mol Cu?
4.0 moles Cu (6.022 X 1023/1 mole Cu) = 2.4 X 1024 atoms of copper ====================
How many moles of silver (Ag) are present in a sample of 3.8 10 to the power of twenty four atoms Ag?
The answer is 6,31 moles Ag.
How many Ag atoms are there in a 88.1 gram sample of Ag?
A 88,1 gram sample of Ag contain 4,9185.10e23 atoms.
How many atoms are present in a 15 mol sample of uranium?
Approx. 9.1024 atoms.
How many atoms are present in 6.81g of copper?
6.81 grams copper (1 mole Cu/63.55 grams)(6.022 X 1023/1 mole Cu) = 6.45 X 1022 atoms of copper ----------------------------------------
How many atoms are there in a copper and what are they?
Copper is an element. You can have a single atom or many atoms and it's still copper.
How many moles are present in 6.022 x 1023 atoms of Cr?
Only one mole of copper.
How many atoms are present in a piece of sterlingsilver jewelry weighing 33.14?
How many atoms are present in a piece of sterlingsilver jewelry weighing 33.14 ? (Sterling silver is a silver-copper alloy containing 92.5% by mass.)
How many atoms are in each elemental sample 4.0mol Cu?
4.0 moles Cu (6.022 X 1023/1 mole Cu) = 2.4 X 1024 atoms of copper ====================
How many atoms of copper are there in 497.3 grams of copper?
The answer is 47,128 x 1023 atoms.
How many atoms are in the element copper and in the element carbon and in the element aluminum and how many atoms are in baking soda and how many atoms are in a sugar cube?
There are no "atoms in an element," but rather atoms OF an element. If you are trying to find the number of atoms in a sample of a pure element you divide its weight by its molar mass and then multiply by 6.022 x 10^23 to get the answer in atoms. The answer options are 2,3, or 4.
How many Cu atoms are present in a piece of sterling-silver jewelry weighing 33.14 g?
This depends on the percentage of copper in the alloy.If this alloy contain 7,5 % Cu the number of copper atoms is approx. 0,2355.10.e+23.
How many copper atoms are in 2.36 of copper?
4.682x10^24
How many moles of silver (Ag) are present in a sample of 3.8 10 to the power of twenty four atoms Ag?
The answer is 6,31 moles Ag.
How many oxygen atoms are there in a molecule of copper nitrate?
The compound copper nitrate has Cu(NO3)2 for a chemical formula. In that formula, we see that there is an NO3 radical present, and that there are 3 atoms of oxygen in that radical (the sub 3 after the O). But there are 2 of those NO3 radicals (the sub 2 outside of the parens) present in this compound. That means that there are 3 x 2 oxygen atoms in a molecule of copper nitrate, or 6 atoms of oxygen in Cu(NO3)2.
