Aneutron is an electrically neutral subatomic particle with a mass just slightly greater than that of a proton. a free neutron is radioactive and decays after a few minutes into other subatomic particles. in one experiment, a neutron at rest was observed to decay into a proton (mass 1.67Γ10^β27kg) and an electron (mass 9.11Γ10β31kg). the proton and electron were shot out back-to-back. the proton speed was measured to be 1.0Γ105 m/s and the electron speed was 3.2Γ107 m/s . no other decay products were detected. a. did momentum appear to be conserved in the decay of this neutron? b. if a neutrino was emitted in the above neutron decay, in which direction did it travel? c. explain your reasoning. d. how much momentum did this neutrino carry away with it?

The vapour pressure of benzene is 53.3 kpa at 60.6 Β°c, but it fell to 51.5 kpa when 19.0 g of a non-volatile organic compound was dissolved in 500 g of benzene. calculate the molar mass of the compound.
