<u>Answer:</u>

<em>The chocolate bar has 30 grams of fat, if it has 270 fat calories. </em>

<u>Explanation:</u>

Nourishment calories are characterized as the measure of warmth vitality required to raise the temperature of one kilogram of water by one degree Celsius.

The micro nutrients in our nourishment like proteins, fats and starches has their particular commitment to the absolute nourishment calorie which was taken by the human.

It is realized that every gram of fat adds to 9 calories in any nourishment thing.

1 g of Fat= 9 fat calories

1 fat calories= 19 g of fat

270 fat calories= 270 \times 19g of fat = 30 g of fat

Thus 270 fat calories will contain 30 g of fat in it.

How many grams of ice at -13 deg C must be added to 711 grams of water that is initially at a temperature of 87 deg C to produce
Basile [38]

Answer:

The answer to your question is m = 4.7 kg

Explanation:

Data

Ice                                   Water

mass = ?                          mass = 711 g

T₁ = -13°C                         T₁ = 87°C

T₂ = 10°C                         T₂ = 10°C

Ch = 2090 J/kg°K          Cw = 4180 J/kg°K

Process

1.- Convert temperature to kelvin

T₁ = 273 + (-13) = 260°K

T₁ water = 87 + 273 = 360 °K

T₂ = 10 + 273 = 283°K

2.- Write the equation of interchange of heat

                 - Heat lost = Heat absorbed

               - mwCw(T₂ - T₁) = miCi(T₂ - T₁)

-Substitution

              - 0.711(4180)(10 - 87) = m(2090)(10 - (-13))

- Simplification

                            228842.46 = 48070m

                            m = 228842.46/48070

-Result

                            m = 4.7 kg

What is the freezing point of an aqueous suger (C12H22O11) solution that boils at 110C°?
AURORKA [14]

Sucrose doesn't show appreciable dissociation in water, so i≈1 in this case. by extension, −7.3°C is the approximate freezing point of this solution.
