How many moles are in 3.4 x 10^-7 molecules of silicon dioxide, SiO2?​

Chemistry
1 answer:
avanturin [10]3 years ago
7 0

Answer:

Approximately 5.646 * 10^-17 moles

Explanation:

Avagardo's number is approximately 6.022 * 10^23 molecules. Therefore, dividing 3.4 * 10^7 by avagadro's number yields approximately 5.646 * 10^-17 moles. Hope this helps

Gwar [14]

Answer:

Sucrose is a disaccharide composed of alpha D gluose and beta D fructose linked together by beta 2,alpha1 glycosidic linkage.

Explanation:

The specificity of glycosidic linkage very much essential to choose the substrate for the synthesis of specific disaccharide.

 For example sucrose contain beta 2,alpha1 glycosidic linkage that means the hydroxyl group of anomeric carbon of one monosaccharide(fructose) should remain in beta conformation and the hydroxyl group of other monosaccharide(glucose) should remain in alpha conformation.

How many grams of Cl2 are in 0.345L at STP?
blsea [12.9K]

Answer: 1.09 g

Explanation:

If we use the approximation that 1 mole is 22.4 L, then setting up a proportion,

  • 1/22.4 = x/0.345 (x is the number of moles in the sample)
  • x = 0.0154 mol

Since the mass of a mole of chlroine is about 70.9 g/mol, (0.0154)(70.9) = 1.09 g (to 3 s.f.)
