Answer: Molecular mass of CH_3COONa is 82 g

Explanation:

Molecular mass (M) is defined as the mass in grams of 1 mole of a substance.

S.I Unit of Molar mass is gram per mole and it is represented as g/mol.

Atomic Mass of Carbon (C) = 12 g

Atomic Mass of hydrogen (H) = 1 g

Atomic Mass of oxygen (O) = 16 g

Atomic Mass of sodium (Na) = 23 g

Molecular mass of CH_3COONa = 12(1)+1(3)+12(1)+16(2)+23(1) = 82 g

Answer:

The correct answer is option C) "Handle your thermometer with care. When you remove it from your drawer be sure to hold both ends of the thermometer so that it does not slip out".

Explanation:

Handling a thermometer with care is part of the laboratory safety precautions that should be considered regarding to the reactivity of metals. Old thermometers are based on the element mercury, a shining metal that is the only element that is in liquid state on room temperature conditions. Mercury is very toxic, and is particularly dangerous because it vaporizes at room temperature and it could be inhaled.

I need help ASAP please
Andrej [43]

525L

Explanation:

Given parameters:

Volume to Temperature ratio = 1.75

Temperature = 300k

Unknown:

Volume of the gas = ?

Solution:

We must carefully analyze and comprehend the detailed description of this experiment:

 It was suggest that the gas could expand or shrink without changing the pressure of the gas inside.

This implies that the pressure in the vessel is constant

This similar to the postulate of the Charles's law: The volume of a fixed mass of gas is directly proportional to the absolute temperature if the pressure is constant.

 Mathematically;

                 \frac{V1}{T1}  = \frac{V2}{T2}

V and T are the volume and temperature

 Now we can solve the given problem;

           \frac{V}{T}  = 1.75

Since temperature is given as 300K

 Input the variables:

           \frac{V}{300}  =  1.75

          V = 1.75 x 300 = 525L
