All of them are wrong, considering significant digits. One cannot take a three digit number and convert it to a more precise number. The last number 0.88atm, is two sig digits, you converted it to a precision of five digits.
Otherwise, the numbers have been manipulated in the calculator correctly, except you believed all those digits the calculator presented.
can you check my answers.
1. What is the corresponding barometric pressure values in mmHg if the barometric pressure is reported as:
29.7 inHg. = 754.38mmHg
31.8 inHg. = 807.72mmHg
26.4 inHg. = 670.56mmHg
22.1 inHg. = 561.34mmHg
34.8 inHg. = 883.92mmHg
2. What are the following equivalents:
746 mmHg = 1014.35 cmH2O.
12.4 psi = 25.22 inHg.
28 cmH2O = 20.58 mmHg.
28 cmH20 = 0.0270 atm.
0.88 atm = 668.80 mmHg.
I'm not too confident about the conversions for #2, but hopefully I did them right.
thanks
