A gas is contained in a thick-walled balloon. When the pressure changes from 45.0 bar to 96.0 bar, the volume changes from 1.20

notsponge [240]

P1 * V1 ÷ T1 = P2 * V2 ÷ T2

45 * 1.20 ÷ 314 = 96 * V2 ÷ 420

30,144 * V2 = 22,680

V2 = 22,680 ÷ 30,144

The new volume is approximately 0.75 liter.

Determine the formula weight of caffeine, C₈H₁₀N₄O₂. Provide an answer to two decimal places.

arlik [135]

Let's find

$\\ \tt\hookrightarrow C_8H_10N_4O_2$

We need accurate mass

$\\ \tt\hookrightarrow 8(12.011)+10(1.007)+4(14.006)+2(16.0)$

$\\ \tt\hookrightarrow 96.088+10.07+56.024+32.0$

$\\ \tt\hookrightarrow 196.182g/mol$

$\\ \tt\hookrightarrow 196.18g/mol\:or 196.18u$

puteri [66]

Answer:

The answer is

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question

mass of rock = 454 g

volume = 100 cm³

The density of the rock is

$density = \frac{454}{100} = \frac{227}{50} \\$

We have the final answer as
