What is for the atomic mass K?
Potassium is a non metal element. Atomic mass of it is 39.
How do you find the mass of a sample of 1.72 x 1023 atoms of potassium?
1 mole K atoms = 39.0983g K (atomic weight in grams)1 mole K atoms = 6.022 x 1023 atoms K (Avogadro's number)Convert known atoms to moles.1.72 x 1023 atoms K x (1mol K/6.022 x 1023 atoms K) = 0.286mol KConvert moles to mass in grams.0.286mol K x (39.0983g K/1mol K) = 11.2g K
What is the mass of a duck?
Which is the best estimate for the mass of a duck?
What is the mass in grams of 0.5 moles of potassium?
The atomic mass of potassium, K is 39.1. This means that 1 mole of potassium has a mass of 39.1g. Mass of 0.5mol of K = 0.5 x 39.1 = 19.6g
How many grams in 1.90 moles of K?
To convert from moles to grams, we need to use the molar mass of the element. The molar mass of potassium (K) is approximately 39.10 g/mol. So, for 1.90 moles of K, the mass would be 1.90 moles * 39.10 g/mol = 74.29 grams.
What is the angular frequency in terms of k and m when finding the oscillation of a spring-mass system?
The angular frequency () in a spring-mass system is calculated using the formula (k/m), where k is the spring constant and m is the mass of the object attached to the spring.
How can you calculate the mass or the volume of 18-k gold?
43L of 18-k gold
What is the mass of K 42 remaining in a 16g sample of 37.2hrs?
To find the mass of K-42 remaining after 37.2 hours, we would need additional information such as the half-life of K-42. Without this information, it is not possible to calculate the remaining mass.
What is the atomic mass of Pottassium?
Standard atomic mass of potasium is 39.0983(1) g·mol−1
What is the relationship of acceleration and the mass of the object according to Newtons second law of Motion?
When force is constant, mass and acceleration are inversely related. ma=k, m=k/a or a=k/m. The smaller the mass, the greater the acceleration. The greater the mass the smaller the acceleration. Because force and acceleration are both vectors, the direction of acceleration is the same as the direction of force.
How would k vary with different mass of trapped gas?
The value of the spring constant ''k'' in a spring-mass system would remain constant regardless of the mass of the trapped gas, as it only depends on the stiffness of the spring and not on the mass attached to it.
What is the formula for calculating the angular frequency () of a system in terms of the mass (m) and the spring constant (k)?
The formula for calculating the angular frequency () of a system in terms of the mass (m) and the spring constant (k) is (k/m).
