1.197*10^(-22)
0.004kg to 4 grams.
The gram molecular mass of carbon tetrachloride is 12.011 + 4(35.453) or 153.823. Each mole contains Avogadro's Number of molecules. Therefore, the number of molecules in 200 grams is (200/153.823) X Avogadro's Number or 7.83 X 1023 molecules, to the justified number of significant digits.
Let "A" be the grams of acetic acid added. Then (A)/(100 + A) = 0.04 That is A=(100 +A)x(0.04) or A-0.04A = 4 (0.96A) = 4 A = 4/(0.96) = 4.166666667 grams
4 moles of oxygen atoms are present in 4 moles of H2O
4
That is 4 Kilograms or 4,000 grams
Let me help you a little: water is H2O
4 ml of water is 4 grams
There are four molecules of water in 4H2O. One molecule of water is written as H2O. The subscript 2 tells you that there are two H(hydrogen) atoms. Since there is no subscript after the O there is one O(oxygen) atom. Now back to 4H2O. The coefficient 4 tells you there are four molecules of H2O. Therefore there are eight H(hydrogen) atoms and four O(oxygen) atoms.
60 grams of water is 4 tbsp.
4 molecules It's Na2CrO4 · 4H2O
There are 8 oxygen atoms in 4 water molecules.
1 tbsp of water is 15 grams.
Approx 113 grams.
For every peptide bond there is one water molecule
20 grams of water is 4 teaspoons.
3/4 cup of water is approximately 170 grams
