Answer:

978.19° C

Explanation:

P1V1/T1 =P2V2/T2     Since the pressure is constant, this can be written as

V1/T1 = V2/T2      RE-ARRANGE TO

V2 *  T1/V1   = T2       Note:  T must be in Kelvin!!

1.5 L  *  (273.15 + 23)  / (.355 L ) = T2 = 1251.338 K  =978.19 C

How many mol of butan-1-ol are in 10.0 mL of butan-1-ol?
ELEN [110]

Answer:

2) 0.109 mol

Explanation:

The density of butan-1-ol is 0.8098g/mL. And its molar mass is: 74.121g/mol.

First, we need to convert volume of butan-1-ol to mass:

10.0mL * (0.8098g / mL) = 8.098g of butan-1-ol

Now, we need to convert these grams to moles using molar mass:

8.098g * (1mol / 74.121g) = 0.109 moles of butan-1-ol

Right answer is:

<h3>2) 0.109 mol </h3>
