Hey there!

<span>Atomic Masses :

H = <span>1.00794  a.m.u
N = </span><span>14.0067  a.m.u
O = </span><span>15.9994  a.m.u

Therefore:

HNO3 = </span>1.00794 + 14.0067 + ( 15.9994 * 3 ) =>  <span>63.0128 g/mol</span>

The property which primarily controls how much water can be present as a gas is:
Assoli18 [71]
The temperature of the air is the property which primarily controls how much water can be present as a gas. 

Meteorology is the study of the atmosphere. It primarily focuses on weather which is defined as the condition of the atmosphere at a certain time and place. It changes every day depending on earth location. There are five factors that affect weather namely, temperature, pressure, humidity, wind and precipitation.

The question above primarily talks about humidity-the amount of water vapor in the air. As the  temperature increases, the air or gas can hold more water. The warmer the air is, the more water it can possibly hold as vapor.

A 55.0-kg skydiver free falls for a period of time before opening his parachute. what is his kinetic energy when he reaches a ve
morpeh [17]
The kinetic energy of a moving object is calculated through the equation,
                                 KE = 0.5mv²
where KE is kinetic energy, m is mass, and v is the velocity. Substituting the known values in the problem above,
                                KE = 0.5(55 kg)(16 m/s)²
                                KE = 7,040 J
Thus, the kinetic energy of the skydiver is approximately equal to 7 kJ.

Mass box A = 10 grams; Mass box B = 5 grams; Mass box C—made of one A and one B Mass ratio A/B =
LUCKY_DIMON [66]

Answer:

mass ratio of A/B is 2:1

Explanation:

Since the mass of box A = 10g

                mass of box B = 5g

   Mass of box C = mass of box A + mass of box

A ratio compares two quantities. To find the ratio of the two boxes:

  Ratio of A to B = \frac{mass of A}{mass of B}

  Ratio of A to B = \frac{10grams}{5grams} = 2

The mass ratio is 2:1 i.e box A has twice the mass of B
