Asample of gas occupies 115.9 ml at -206.6°c. what volume does the sample occupy at 175.9 °c? select one: a. 17.2 b. 782 c. -108 d. -169

Charles law gives the relationship between volume of gas and temperature.
It states that for a fixed amount of gas at constant pressure, volume of gas is directly proportional to the temperature.

where V - volume and T - temperature and k - constant 

where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
T1 - temperature in Kelvin , -206.6 °C + 273.15 = 66.55 K
T2 - 175.9 °C + 273.15 = 449.05 K
substituting the values in the equation 

V = 782 mL
the new volume is 782 mL

Ch4 is nonpolar and insoluble in water. since all of the hydrogen atoms are evenly spread around the carbon atom even through the c h bond is polar all the poles cancel each other out.
