(0.50M)(3.50mL) = c2(75.00)

c2= 2.3e-2

Is this correct?

Yes this appears to be

What about (0.50)(1.75) = c2(75.00)

c2=1.16e-2.

Is this correct in terms of correct number of sig figs?

Ok try the problem again then comeback something is off you sisnt multiply incorrectly did you

I got 0.011666667 so for correct sig figs is that 1.16e-2 or 1.1e-2?

1.1e it diesnt have six in the answer

So are you saying that's not the answer????

To check if your answer is correct, let's perform the calculations and compare the results.

Given:
(0.50 M) (3.50 mL) = c2 (75.00)

On the left side of the equation, we have the concentration (0.50 M) multiplied by the volume (3.50 mL). To calculate this, simply multiply the two values:
(0.50 M) * (3.50 mL) = 1.75 mol

On the right side of the equation, we have c2 (75.00). From the information given, c2 = 2.3e-2. So, let's substitute this value:
2.3e-2 * (75.00) ≈ 1.72

Therefore, the result on the left side of the equation is approximately 1.75 mol, and on the right side, it is approximately 1.72. It seems like there might be a slight discrepancy between the two values.

To determine if your answer is correct, we need to consider the level of accuracy expected. If the given values and calculations are rounded to the appropriate significant figures, it is possible that your answer is within an acceptable range. However, this depends on the level of precision and accuracy required for the specific problem or context.

In conclusion, while there appears to be a slight discrepancy between the two sides of the equation, the accuracy of your answer depends on the specific requirements of the problem.
