Just because it has the prefix "oxi" it doesn't necessarily mean that oxygen exists as a reactant.

Making and breaking ionic compounds happen right before or after redox reactions after the atoms or ions are modified into one another.

sattari [20]

Step $1$

<u>find the mass of a single washer</u>

Divide the total mass by the number of washers

$\frac{0.4168}{1000} =0.0004168\ Kg$

$0.0004168kg=4.168*10^{-4} kg$

Step $2$

<u>Convert kg to mg</u>

we know that

$1 kg=1*10^{6} mg$

$4.168*10^{-4}*10^{6} =4.168*10^{2}mg=416.8 mg$

therefore

<u>the answer is</u>

$416.8 mg$

zhannawk [14.2K]

Answer:

Explanation:

The new volume can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

Since we're finding the new volume

$V_2 = \frac{P_1V_1}{P_2} \\$

We have

$V_2 = \frac{195000 \times 3.5}{150000} = \frac{682500}{150000} \\ = 4.55$

We have the final answer as
