Explanation:
The Mass of ice is 69.12g.
What is mass?
It is a dimensionless quantity that expresses a particle or object's mass. The accepted unit of mass under the International System (SI) is the kilogram.
What is temperature?
Temperature is a measure of the average kinetic energy of the particles inside an object. The temperature increases cause these particles to move more quickly. It is possible to measure temperature using a thermometer or a calorimeter.
first calculate the amount of heat as follows;
q= mass of water C= (0°C-55°C)
=100.0g (4.186J/g°c) (-55°C)
=-23023J
Heat lost by water is gained by ice,
-q=m*ΔH
-23023J= m*333J/g
= 69.12g
Therefore, Mass of ice is 69.12g.

Answer:
Density of aluminum is 2.699 g/cm^3
Explanation:
Density of a given material can be defined as the mass of the substance present in a unit volume. Mathematically it can be expressed as:
Units: g/cm^3 or kg/m^3
Aluminum (Al) is one the lightest element and is known to have a density of 2.699 g/cm^3
Answer:
There is only one formula to use and we should assume ideal gas. This equation is: PV=nRT. For the following questions manipulate this equation to get the answer.
1. n = PV/RT = (249*1000 Pa)(15.6 L)(1 m^3/1000 L)/(8.314 Pa-m^3/mol-K))(21+273) = 1.59 mol
2. P = nRT/V = (1.59)(8.314)(51+273)/(15.6/1000)(1000) = 274.55 kPa
3. Since the answer in #2 is more than 269 kPa, then the tires will likely burst. 4. Reduce pressure way below the limit 269 kPa.
