Acertain crunch cereal contains 11.0 grams of sugar(sucrose, c12h22o11) per serving size of 60.0 gram. how many
servings of this cerael must be eaten to consume 0.0278 moles of sugar?

51.859 grams

Explanation:

Given:

Mass of sugar in the crunch cereal per serving= 11.0 grams

Mass of cereal served per serving = 60.0 grams

Molar mass of the sugar (C₁₂H₂₂O₁₁) = ( 12 × 12 + 22 × 1 + 16 × 11 ) = 342 grams

Number of moles of sugar per serving = Mass / Molar mass

= 11.0 / 342

= 0.03216 moles

Now,

0.03216 moles sugar requires 60 grams cereal

for 0.0278 moles of sugar, cereal required = (60 / 0.03216) × 0.0278

or

for 0.0278 moles of sugar, cereal required = 51.859 grams

43.452

step-by-step explanation:

284 times .153 = 43.452

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
