The volume in liters of 576 grams of SO2 gas at STP is calculated as below
calculate the moles of SO2 = mass/molar mass
= 576 g/64 g /mol = 9 moles
At STP 1mole =22.4 L
what 9 mole =? liters
by cross multiplication
= 22.4 L x 9 moles/ 1moles = 201.6 liters
Answer:
1.1
Explanation:
The slope of a line can be calculated using the values of the x and y corrdinates. The equation is given as;
M = ΔY / ΔX = Y2 - Y1 / X2 - X1
From the points;
(25.6cm³ , 28.16g) - (X1, Y1)
(17.3cm³, 19.03g) - (X2, Y2)
Inserting the values into the equation;
M = 19.03 - 28.16 / 17.3 - 25.6
M = -9.13 / -8.3 = 1.1
10 because you divide 200 by 20
The ionization energy increases because the ratio of the protons to electrons increases. It is quantitatively expressed in symbols as X + energy → X+ + e−.
