4. Calculate the following:
a) 2.34 x 1065 cm +9.2 x 1066 cm
b) 313.0 kg - 1.2 x 103 g

a). 12 299.3 centimeters

b). 312.8764 kilograms

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.
