Using charles law
v1/t1=v2/t2
v1=1l
v2=1.1l
t2=255+273=528
t1=?
1/t1=1.1/528   
cross multiply
1.1t1=528 divide both sides by 1.1
t1=528/1.1
t1=480k or 207celcius

Answer : The initial temperature of gas is 207^oC

Explanation :

Charles's Law : It is defined as the volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

V\propto T

or,

\frac{V_1}{T_1}=\frac{V_2}{T_2}

where,

V_1 = initial volume of gas = 1.00 L

V_2 = final volume of gas = 1.10 L

T_1 = initial temperature of gas = ?

T_2 = final temperature of gas = 255.0^oC=273+255.0=528.0K

Now put all the given values in the above equation, we get:

\frac{1.00L}{T_1}=\frac{1.10L}{528.0K}

T_1=480K=480-273=207^oC

Therefore, the initial temperature of gas is 207^oC

Does anyone know how to find mass of NaN3?
Alexus [3.1K]
The molar mass (atomic weight ) of sodium is 23.0 grams/mole and the molar mass of sodium azide, NaN3 , is the mass of sodium, 23.0 gram/mole added to the molar mass of three atoms of nitrogen (14.0 x 3 = 42 gram/mole) which equals 65.0 grams/mole. The percentage of sodium is 23.0 /65.0 x 100 % = 35 %

Verizon [17]

Answer:

V=?

S=25m

t=2.5s

V=S/t

V=25/2.5

V=10m/s

So, the ball was traveling with the speed of 10m/s.
