This measurement converter chart will help you figure out the liquid measurements called for.

0.5 ml = ⅛ teaspoon.

1 ml = ¼ teaspoon.

2 ml = ½ teaspoon.

5 ml = 1 teaspoon.

15 ml = 1 tablespoon.

25 ml = 2 tablespoons.

50 ml = 2 fluid ounces = ¼ cup.

75 ml = 3 fluid ounces = ⅓ cup.

A 48.3 mL sample of gas in a cylinder is warmed from 22 °C to
goldenfox [79]

Answer:

58.94 mL

Explanation:

V1 = 48.3 mL             V2 = v mL

T1 = 22 degree celsius OR 295 k         T2 = 87 degree celsius OR 360 k

We will use the gas equation:

PV = nRT

Since the Pressure (p) , number of moles (n) and the universal gas constant(R) are all constants in this given scenario,

we can say that

V / T = k , (where k is a constant)

Since this is the first case,

V1 / T1 = k --------------------(1)

For case 2:

Since we have the same constants, the equation will be the same

V / T = k (where k is the same constant from before)

V2 / T2 = k (Since this is the second case) ------------------(2)

From (1) and (2):

V1 / T1 = V2 / T2

Now, replacing the variables with the given values

48.3 / 295 = v / 360

v = 48.3*360 / 295

v = 58.94 mL

Therefore, the final volume of the gas is 58.94 mL
