How many moles of glucose are in 19.1 g of glucose

Chemistry

WINSTONCH [101]4 years ago
7 0

Answer:

There are 0,106 mol of glucose in 19,1g.

Explanation:

First we calculate the weight of 1 mole of Glucose whose molecular formula is C6 H12 0 6, with the atomic weights of each element obtained from the periodic table. Then, by means of a simple rule of three we calculate the moles that are in 19.1 grams:

Weight 1 mol C6H1206 = (Weight C)x 6 + (Weight H)x12 + (Weight 0)x6=

                                       = 12 g x 6 + 1g x12 + 16 g x 6= 180 g/mol

180 g ----1 mol glucose

19,1 g-----x= (19,1 g x 1 mol glucose)/ 180 g= <em>0,106 mol</em>

aliya0001 [1]
<span>There are a number of ways to express concentration of a solution. This includes molarity. It is expressed as the number of moles of solute per volume of the solution.  To convert the mass of the solute to moles, we use the molar mass of the substance. We calculate as follows:

MOlarity = 4.725 g ( 1 mol / 58.45 g ) / .5 L = 0.162 mol / L</span>

Both protons and neutrons (and their anti-particles) froze out:
VladimirAG [237]
I think Both protons and neutrons (and their anti-particles) froze out at 1013 K, about 0.0001 seconds after the Big Bang. Protons and neutrons are sub atomic particles of an atom that are found in the nucleus of an atom. Proton is the positively charge particle while the neutron has no charge. The proton positive charge accounts for the positive nuclear charge.
