How many grams are equal to 450 milligrams?

Answer 1

Molarity = moles of solute/Liters of solution ( 450 ml = 0.450 liters)

5M C6H12O6 = moles C6H12O6/0.450 liters

= 2.25 moles C6H12O6 (180.156 grams/1 mole C6H12O6)

= 405.351 grams of glucose ( you do significant figures )

Answer 2

450 millimoles is 0.45 moles. The formula is no. moles is mass/molecular mass. The molecular weight of glucose is 180g/mol. Therefore 0.45 x 180 is 81 grams.

Answer 3

1-millimole (mmol) equals .001-moles (mol). Therefore 450-mmol equals .450-mol. 180.16-g/mol multiplied by .450-mmol equals the answer of 81-grams (using 2 significant figures).

Answer 4

450 milligrams is less than a gram. There is 0.54 grams in 450mg

Answer 5
