What is the percent error for a measured value of 3.24 and a correct value of 3.02?
Percent error is calculated using the formula: ((measured value - correct value) / correct value) x 100. Plugging in the values, we get ((3.24 - 3.02) / 3.02) x 100 = (0.22 / 3.02) x 100 ≈ 7.28%.
How many moles of washing soda are there in 5g?
To find the moles of washing soda in 5g, you need to know its molar mass. Washing soda (Na2CO3) has a molar mass of approximately 105.99 g/mol. Using this, you can then calculate that there are approximately 0.047 moles of washing soda in 5g.
What is the percent of error in evaluating the molecular mass of a compound if the experimental value was 105.2 amu and the known value was 107.5 amu?
The percent error is calculated using the formula: |(experimental value - known value) / known value| x 100. Plugging in the values: |(105.2 - 107.5) / 107.5| x 100 ≈ |-2.3 / 107.5| x 100 ≈ 0.021 x 100 = 2.1% Therefore, the percent error in evaluating the molecular mass of the compound is approximately 2.1%.
How do you calculate percent inhibition?
Percent inhibition can be calculated using the formula: % Inhibition = [(Control value - Sample value) / Control value] x 100. First, subtract the sample value from the control value, then divide that result by the control value, and finally multiply by 100 to express it as a percentage.
Formula to calculate weight for circle plate?
The formula to calculate the weight of a circle plate is weight = density x volume, where density is the material density and volume is calculated as π x (radius^2) x thickness.
What is the molecular weight of Na2CO3?
The molar mass of Na2CO3 (sodium carbonate) is calculated by adding the atomic masses of sodium (Na), carbon (C), and oxygen (O) in the compound. The molar mass is approximately 105.99 g/mol.
What is the formula for relative error?
The formula for relative error is:Erel= |x-x*| / |x|, where x is the proper value, and x* an approximate value.
What is the percent error for a measured value of 3.24 and a correct value of 3.02?
Percent error is calculated using the formula: ((measured value - correct value) / correct value) x 100. Plugging in the values, we get ((3.24 - 3.02) / 3.02) x 100 = (0.22 / 3.02) x 100 ≈ 7.28%.
Formula for z-test?
The z score is calculated from the distance of a value from the distribution center divided by the standard dev. (x-xbar)/st. dev
Formula of a triangle?
The value of x is
What is the formula to find x value?
The formula to find the value of X would be Y-2X. This would equal to y-9 times 2 X.
What is the formula for the area of an isosceles triangle?
The are of any triangle is calculated by the formula: Area = 1/2 x Base x Height
What is the formula for horizon value?
The formula for horizon value is often calculated as the perpetuity value of a business at the end of a forecast period. It is typically calculated using the Gordon Growth Model, which is V = (FCF x (1 + g)) / (r - g), where V is the horizon value, FCF is the free cash flow at the end of the forecast period, g is the perpetual growth rate, and r is the discount rate.
What is the formula for x-bar in statistics?
(x value) - average

Z-score responding to 10 hours?
The z-score can't be calculated with the information given. A mean & standard deviation is required to put into the formula: Z = (x-mean)/sigma. Your x value is 10.
Percent error of O in MgO?
To calculate the percent error of oxygen in magnesium oxide (MgO), you would compare the experimental value of oxygen in MgO to the theoretical value. The experimental value can be determined by chemical analysis, while the theoretical value can be calculated using the molecular formula of MgO. The percent error is calculated using the formula: (|Theoretical value - Experimental value| / Theoretical value) x 100%.
