Mass number minus the atomic number equals the number of neutrons. Mass number is the number of particles in an atom that have significant mass. Electrons are assigned a valâ¦ue of 0 since the mass is so much smaller than protons and neutrons. Protons and neutrons are similar in mass and are assigned mass number of 1.
Why Uber is losing so much money? The biggest part of the problem is that Uber is a relative small fish in the market and is not getting nearly enough customers. According to analyst reports, as of August 2015, Didi Kuaidi completed seven million rides as opposed to Uber's one million.
To put it bluntly: the reason why Uber has so much cash is because, well, governments no longer do. Instead, this money is parked in the offshore accounts of Silicon Valley and Wall Street firms. Look at Apple, which has recently announced that it sits on $200bn of potentially taxable overseas cash, or Facebook, which has just posted record profits of $3.69bn for 2015.
