At the end of the school year a high school chemistry teacher asks one of his/her students to stay after school and help clean the storage room. While cleaning, the student finds a rectangular block of metal that is not labeled and is therefore unknown. The teacher challenges the student to identify the metal using density. The student measures each side of the block (using a centimeter ruler) and determines the length is 3.00 cm, height is 5.00 cm, and width is 5.00 cm. The student then takes the mass of the block using a centigram balance and reports the mass as 337.50 g. The student then researched the density of different materials. Metal Density Tantalum 16.67 g/cm Tantalum 16.667 g/cm Titanium 4.50 g/cm Titanium 5 g/cm What is the identity of the unknown metals and gives the most appropriate answer given the data as measured by the student? O A The unknown metal is tantalum because the density of tantalum is 16.67g/cm^3, The number reported by the student uses the proper number of significant figures based on the precision of the scientific equipment. B. The unknown metal is tantalum because the density of tantalum is 16.667 g/cm^3. The number reported by the student uses the proper number of significant figures

General Chemistry (Quesion -6) =====================
If the enzyme lactase has a Vo of 0.111111111111 mM per minute when [S] = 1.0 mM, and a Vo of 0.20 mM per minute when [S] = 5.0 mM, what is its Km? Calculate Vmax of the above enzyme (lactase). Calculate the slope on a Lineweaver-Burk plot (Km/Kmax) for the above enzyme (lactase).

please help this is my 4th time posting this and i havent gotten a correct answer. Please actually draw the graph out. A newly discovered enzyme, MBCase, cleaves carbon-carbon bonds of vicinal alcohol; The kinetic parameters were measured for 1.0 nM Of MBGase and determined to be a Km = 10 nM and a kcat = 100 s-1 a.) Sketch the graph out as a double-reciprocal plot (Lineweaver-Burke Plot) and label: -the axes (with units) -the point on the curve that can be used to determine Km -the point on the curve that can be used to determine Vmax
