Based on the $${\mathrm{Al}}_2{\mathrm{O}}_3?{\mathrm{SiO}}_2$$ phase diagram shown below, determine the wt\% of phases present for $${\mathrm{Al}}_2{\mathrm{O}}_3?55$$ wt\% $${\mathrm{SiO}}_2$$ over the $$1900^{?}\mathrm{C}$$ to $$1500^{?}\mathrm{C}$$ temperature range (use $$100^{?}\mathrm{C}$$ increments). (Round the final answer to nearest whole number) The wt\% of phases present for $${\mathrm{Al}}_2{\mathrm{O}}_3?55\mathrm{wt}\%{\mathrm{SiO}}_2$$ over the $$1900^{?}\mathrm{C}$$ to $$1500^{?}\mathrm{C}$$ is as follows: At $$1500^{?}\mathrm{C}$$, $$\mathrm{Wt}\%=$$ \% liquid At $$1600^{?}\mathrm{C}$$. $$\mathrm{Wt}\%=$$ At $$1700^{?}\mathrm{C}$$, $$\mathrm{Wt}\%=$$ \% liquid At $$1800^{?}\mathrm{C},$$ \% liquid At $$1900^{?}\mathrm{C}$$ $$\mathrm{Wt}\%=$$ \% liquid
