Answer:

The calories required = 35088

Explanation:

The heat required can be calculated by using specific heat of the water and mass and temperature raised.

The specific heat of water is the amount of heat required to raise the temperature of one gram of water by one degree celsius

Thus

Heat required = mass of water X specific heat X change in temperature

Given:

Specific heat of water = 1 cal /g °C

mass of water = 731 g

change in temperature = 83-35 = 48°C

Putting values

Q=731X1X48=35088cal=35.088kcal

Sonbull [250]

Answer:

There are 1.8021 ⋅ 1024 molecules of CH4 in 48 grams of CH4. To answer this question, you must understand how to convert grams of a molecule into the number of molecules. To do this, you have to utilize the concepts of moles and molar mass. A mole is just a unit of measurement. Avogadro's number is equal to 6.022 ⋅1023 molecules/mole. i think please dont complain to me if its wrong im sorry
