A sunscreen preparation contains 2.50% benzyl salicylate by mass. If a tube contains 4.0 oz
antoniya [11.8K]

About 0.92 kg of benzyl salicylate would be needed in order to manufacture 325 tubes of sunscreen.

A tube contains 4.0 oz of the sunscreen and each one 2.5% benzyl salicylate.

         2.5% of 4.0 oz = 0.1 oz

Thus, each tube would need 0.1 oz of benzyl salicylate.

325 tubes of the sunscreen is needed and each one requires 0.1 oz of benzyl salicylate. Hence, total amount of benzyl salicylate needed would be:

    325 x 0.1 oz = 32.5 oz

From conversion:

16 oz = 1 lb

Hence,

32.5 oz = 32.5/16

                        = 2.03 lb

Also:

2.205 lb = 1 kg

2.03 lb = 2.03/2.205

             = 0.92 kg

If 1.2 moles of ideal gas occupy a volume of 18.2 L at a pressure of 1.8 ATM what is the temperature of gas in degrees Celsius.
Novosadov [1.4K]

Answer: A 59.5 degree celcius

The equation that we will use to solve this problem is :

PV = nRT where:

P is the pressure of gas = 1.8 atm

V is the volume of gas = 18.2 liters

n is the number of moles of gas = 1.2 moles

R is the gas constant =  0.0821

T is the temperature required (calculated in kelvin)

Using these values to substitute in the equation, we find that:

(1.8)(18.2) = (1.2)(0.0821)(T)

T = 332.5 degree kelvin

The last step is to convert the degree kelvin into degree celcius:

T = 332.5 - 273 = 59.5 degree celcius
