Answer:

T2=276K

Explanation:

Given:

Initial volume of the balloon V1 = 348 mL

Initial temperature of the balloon T1 = 255C

Final volume of the balloon V2 = 322 mL

Final temperature of the balloon T2 =

To calculate T1 in kelvin

T1= 25+273=298K

Based on Charles law, which states that the volume of a given mass of a ideal gas is directly proportional to the temperature provided that the pressure is constant. It can be applied using the below formula

(V1/T1)=(V2/T2)

T2=( V2*T1)/V1

T2=(322*298)/348

T2=276K

Hence, the temperature of the freezer is 276 K

How many moles are in 28g of Fe2O3
nlexa [21]

Find the molar mass of Fe_2O_3

2Fe = 2*56 = 112

3O = 3* 16 =    48

Molar Mass = 160 grams

moles= given mass / molar mass

moles = 28 / 160

moles = 0.175   <<<< answer
