The volumes of gases A, B, C and D are in the ratio, 1:2:2:4 under the same conditions of temperature and pressure. If the volume of A is actuaally 5.6 dm3 at s.t.p calculate the number of molecules in the actual volume of D ate s.t.p
Using your answer from (iv), state the mass of D if the gas is dinitrogen oxide `(N_(2)O)`
. (N = 14, O = 16)

Explanation

To solve the problem step by step, we will follow these calculations:

### Step 1: Determine the volumes of gases A, B, C, and D
Given the volume ratio of gases A, B, C, and D is 1:2:2:4, we can express their volumes in terms of the volume of gas A.

Let:
- Volume of A = 1x
- Volume of B = 2x
