Answer:
37.1 g of Arsenic
Explanation:
2.98 x 10^21 atoms of Arsenic x 74.92g/6.02 x 10^23
= 223.26 x 10^21/6.02 x 10^23
= 2.2326 x 10^23/6.02 x 10^23
= 37.1 g of Arsenic
Answer:
refractive index . It is denoted by mew (u).
u = sin i / sin r
It is a unitless and dimensionless quantity. It is just a number.
1.velocity-displacement. The first two equations of motioneach describe one kinematic variable as a function of time. ... Velocity is directly proportional to time when acceleration is constant (v ∝ t). Displacement is proportional to time squared when acceleration is constant (s ∝ t2).
