Answer:
Explanation:
1 ST METHOD
GIVEN DATA:
number of molecules=6.022×10²²molecules
Avogodro's number Na=6.022×10²²
TO FIND:
number of moles
SOLUTION:
As we knom that number of moles=number of molecules/Na
number of moles=6.022×10²²/6.022×10²²
number of moles=1 moles
2ND METHOD:
AS WE KNOW THAT A MOLE OF A SUBSTANCE CONTAINS 6.022×10²² PARTICLES OF THAT SUBATANCE SO
1MOLE OF CO2=6.022×10²²MOLECULES OF CO2
Answer:
a) 9424797000 m3
b) 9424797000000 liters
c) 9424797000000 kg
Explanation
Cylinder has a radius of 1 km= 1000 m.
Area Cylinder = π r^2 = 3,141599* (1000m)^2 = 3141599 m2
a) Volume Cylinder= area x Height=3141599 m2* 3000 m= 9424797000 m3
b) 1000 liters= 1m3, 9424797000 * 1000 = 9424797000000 liters
c) densiy = 1000 kg/m3, or 1 kg/ liter, mass= 9424797000 lt * 1kg/lt =
9424797000 kg
Answer:
In addition, carbonated beverages may serve as an acid load and thus may raise gastric acid volume, leading to increased likelihood of gastro‐oesophageal reflux. Two studies have demonstrated that carbonated beverages can reduce the oesophageal pH < 4 and potentially cause GERD‐related symptoms.
Explanation:
Answer:
<h2>5 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>5 m/s²</h3>
