How many milliliters of 0.260 m na2s are needed to react with 35.00 ml of 0.315 m agno3?
allochka39001 [22]

The complete balanced chemical reaction is:

2 AgNO3 + Na2S --> 2 NaNO3 + Ag2S

 

First let us calculate the number of moles of AgNO3.

moles AgNO3 = 0.315 M * 0.035 L

moles AgNO3 = 0.011025 mol

 

From the reaction, 1 mole of Na2S is needed for every 2 moles of AgNO3 hence:

moles Na2S required = 0.011025 mol AgNO3 * (1 mol Na2S / 2 mol AgNO3)

moles Na2S required = 5.5125 x 10^-3 mol

 

Therefore volume required is:

volume Na2S = 5.5125 x 10^-3 mol / 0.260 M

<span>volume Na2S = 0.0212 L = 21.2 mL</span>

competed in a track meet and you run the 1500m race in 403 s. what was your average speed in miles per hour
laila [671]

Answer:

403 Seconds in Minutes is about 6 minutes.

Explanation:

Now, because I don't know if you're labeling your 1500 as meters or miles, I'm assuming it's miles.

I'm going to take a gander at your question.

Since you're technically going so fast for some odd reason.

Your answer should most definitely be 403 MPH
