a gas of 19 ml at a pressure of 740 mmhg can be expected to change its pressure when its volume changes to 30. ml. express its new pressure in units of atmospheres.

a. 0.61 atm
b. 1.5 atm
c. 470 atm
d. 590 atm

To solve this we assume

that the gas is an ideal gas. Then, we can use the ideal gas equation which is

expressed as PV = nRT. At a constant temperature and number of moles of the gas

the product of PV is equal to some constant. At another set of condition of

temperature, the constant is still the same. Calculations are as follows:

P1V1 =P2V2

P2 = P1V1/V2

P2 = 740mmhg x 19 mL / 30 mL

P2 = 468.67 mmHg = 0.62 atm

im pretty sure its b

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
