Calculate the number of grams in 0.586 mole of each of the following substances?

a) Water, H2O.

= ___ g H2O

b) Glucose, C6H12O6, a sugar in grape juice and honey.

= g C6H12O6

c) Methane, CH4.

= g CH4

Explanation:

H2O: 18.015 g/mol

0.586 mol H2O x 18.015 g/mol H2O x 1 mol H20 = 10.557 g H20

C6H12O6: 180.156 g/mol

0.586 mol C6H12O6 x 180.156 g/mol C6H12O6 x 1 mol = 105.571 g C6H12O6

CH4: 16.043 g/mol

0.586 mol CH4 x 16.043 g/mol x 1 mol CH4 = 9.401 g CH4

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
