Question

P total=P1+P2+P3

 

P container A =3x287kPa

=861 kPa

 

P container B= 1/3*429kPa

= 143 kPa

 

P total=861 kPa+143 kPa

= 1004 kPa

 

Apply the significant figure rule to the final answer.

» Significant Figure Rules 01 >> All manzere digits are significant. Zeres that appear between other HOMZETA digits are always significant. Zeros that appear in front of all of the nonzero daits are called left-end zeros. Left-end zeros are never significant. Zeros that appear after all nonzero digits are called right-end zeros. à decimal point are not significant. Right-end zeros in a number with a This is true whether the seres occur before or after the decimal point. 337 has three significant figures. 1.897 has four significant figures. 39,004 has five significant figures. 5.02 has three significant figures. 0.008 has one significant figure. 0.000416 has three significant figures. 140 has two significant figures. 75,310 has four significant figures. 620.0 has four significant figures. 19.000 has five significant figures. For multiplication and division problems, the answer should be rounded to the same number of significant figures as the measurement with the least number of significant figures. For addition and subtraction problems, the answer should be rounded to the same number of decimal places as the measurement with the least number of decimal places 1
