A sample of gas is held at 1000C at a volume of 20 L. If the volume is increased to 40 L, what is the new temperature of the gas
kaheart [24]

Answer:

The new temperature will be 2546 K or 2273 °C

Explanation:

Step 1: Data given

The initial temperature = 1000 °C =1273 K

The volume = 20L

The volume increases to 40 L

Step 2: Calculate the new temperature

V1/T1 = V2/T2

⇒with V1 = the initial volume = 20L

⇒with T1 = the initial temperature = 1273 K

⇒with V2 = the increased volume = 40L

⇒with T2 = the new temperature = TO BE DETERMINED

20L/ 1273 K = 40L / T2

T2 = 40L / (20L/1273K)

T2 = 2546 K

The new temperature will be 2546 K

This is 2546-273 = 2273 °C

Since the volume is doubled, the temperature is doubled as well

How many moles in one gram of Calcium ??
kirill [66]

Answer:

0.0249 moles in 1 g of Ca

Explanation:

Let's think in the molar mass of Ca.

Ca = 40.08 g/mol

So 1 mol weighs 40.08 grams, or in the opposite 40.08 grams is the weigh of 1 mol

The rule of three will be:

40.08 g are contained in 1 mol

1 g may be contained in (1 . 1) / 40.08 = 0.0249 moles
