Answer:

22.6g/mL

Explanation:

density = mass / volume

given mass of object : 142.5040

volume of object : not given however we are told that when placed inside of a cylinder with 25 mL of water the water level rises to 31.3 mL

31.3 - 25 = 6.3

So the water level rose by 6.3 mL meaning that the object has a volume of 6.3 mL

Now to find the density.

Recall that density = mass / volume

mass = 142.5040 g and volume = 6.3 mL

so density = 142.5040g / 6.3 mL = 22.6 g / ml

SVETLANKA909090 [29]

Answer:

The 200 grams of carbohydrate would this convert to 800 kcals in a day.

Explanation:

Carbohydrates are the source of energy. The metabolism of 1 gram of carbohydrates gives 4 kcals of energy.

If 200 grams of carbohydrate is consumed in a day, then the energy provided by it is:-

Energy\ provided\ by\ the\ carbohydrate = 200\times 4\ kcals=800\ kcals

<u>The 200 grams of carbohydrate would this convert to 800 kcals in a day.</u>

klio [65]

Answer:

704.6 g CO2

Explanation:

MM sucrose = 342.3 g/mol

MM CO2 = 44.01 g/mol

g CO2 = 456.7 g sucrose x (1 mol sucrose/MM sucrose) x (12 moles CO2/1 mol sucrose) x (MM CO2/1mol CO2) = 704.6 g CO2
