fomenos3 years ago
6 0

Answer:

D = 5.3 g/mL

Explanation:

Density = Mass over Volume

D = m/V

Step 1: Define

D = unknown

m = 16 g

v = 3.0 mL

Step 2: Substitute and Evaluate

D = 16 g / 3.0 mL

D = 5.333333333 g/mL

Step 3: Simplify

We have 2 sig figs.

5.333333333 g/mL ≈ 5.3 g/mL

what is the molar mass of nicotine (C10H14N2)? Question 6 options: 14.11 g/mol 28.02 g/mol C 120.1 g/mol 162.2 g/mol C
viva [34]

Answer:

162.2 g/mol

Explanation:

Molar mass is defined as the mass in 1 mole of the substance. It is calculated by adding the molar mass of the substituents each multiplied by the subscript they have in the formula.

Thus, To calculate molar mass of nicotine having formula, C_{10}H_{14}N_2

Molar mass of C = 12.0107 g/mol

Molar mass of H = 1.00784 g/mol

Molar mass of N = 14.0067 g/mol

Thus, molar mass of nicotine = 12.0107\times 10+1.00784\times 14+14.0067\times 2 = 162.2 g/mol

1. Moby travels down a halfpipe on his skateboard in five seconds. His speed at the bottom is 10 m/s. What was his
pshichka [43]

The acceleration of Moby is 2 m/s²

<u>Explanation:</u>

Given:

Time, t = 5 seconds

Velocity, v = 10 m/s

Acceleration ,a = ?

We know:

Acceleration = \frac{velocity}{time}

On substituting the value we get:

a = \frac{10}{5} \\\\a = 2 m/s^2

Therefore, the acceleration of Moby is 2 m/s²

Mole Conversion: What is the mass of 5 moles of O3?​​
Inessa05 [86]

240g

Explanation:

Number of moles = 5

Molar Mass = 16 x 3 = 48

Number of moles = Mass/Molar Mass

Mass = Number of moles x Molar Mass

Mass = 5 x 48

Mass = 240g
