When a food label reads low-calorie, the product contains 40 calories or less per serving.
A calorie is a unit of energy. For historical reasons, two main definitions of "calorie" are widely used. A staple calorie, food calorie, or kilogram calorie was originally defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. Wikipedia
The amount of energy in food and drink is expressed in calories. When we eat or drink more calories than we consume, our bodies store the excess as body fat. If this continues, it can lead to weight gain over time.

Answer:
the pressure of the gas in torr is 2280 torr
Explanation:
The pressure of a gas in torr can be calculated by converting its pressure in kPa to atmospheres and then converting the atmospheric pressure to torr.
One atmosphere is equal to 101.325 kPa. Therefore, the pressure of the gas in atmospheres is 305 kPa / 101.325 kPa/atm = 3.00 atm.
One torr is equal to 1/760 of an atmosphere. Therefore, the pressure of the gas in torr is 3.00 atm * 760 torr/atm = 2280 torr.
Therefore, the pressure of the gas in torr is 2280 torr
